1 Claim. (Cl.

This invention relates to. .va chair and desk combination and more particularly to schoolroom chair and desk for use by students.

An object of this invention is to provide a combination of this type which is so constructed that only two sizes will be necessary so that it may be used by the same student throughout his school period, the chair and desk combination being of such construction that the height of the seat and the relationship of the top to the seat may be adjusted to accommodate the physical characteristics of the students.

In the arrangement of desks at present availablegthere is an objectionable feature present in the lack of leg room due to the position of the seat and top supporting mechanism and other elements used as connecting means. It is therefore, another object of this invention to provide a desk wherein the elements below the top have been removed and those below the seat have been so arranged as to remove all leg obstructions, thereby permitting the positioning of the desks more closely together.

A further object of this invention is to provide a desk wherein the seat or top supporting standard is positioned at one side of the base, seat or top and is vertically adjustable through the medium of adjustable interengaging or locking elements which are automatically locked together in their adjusted position by the offset weight of the elements positioned above the pedestal or connections at the floor.

A still further object oi this invention is to provide an adjustable seat supporting pedestal which is adapted to be vertically adjusted by a step by step or progressive movement of the vide means whereby the level ofv the desk ele--A ment may be readily adjusted to overcome irregularities inthe floor.

Another object of this invention is to provide a desk and adjustable supporting means therefor which is so arranged relative to the seat that vertical adjustment of the desk will simultaneously adjust the rear edge of the desk forward or backward relative to the seat. In this manner raising of the desk to accommodate a larger student will also shift the desk forwardly to give more body room between the desk and the seat, and lowering of the desk for a smaller person will simultaneously reduceV the body room or space. Y

A further object of this invention aims to provide an adjusting means for the desk relative to the seat wherein the adjusting means is at one side of the desk and seat so as topermit free entrance to the seat from one side thereof.

A further object of this invention is to provide a combined desk supporting and adjusting structure which is so arranged and constructed that the desk maybe adjusted by a step by step movement similar to the adjustment of the seat relative to the pedestal wherein the adjusting means is automatically locked in adjusted position by the offset weight of the desk.

A further object of this invention is to provide a desk having readily removable supporting devices which if broken, may be easily replaced without making it necessary to replace the entire desk and seat structure.

A further object of this invention is to provide a desk wherein the student maymake his own adjustment of the seat and the top, and wherein the seat and top by reason of the offset weight thereof, Vwill remain in adjusted position irre'- the provision of a desk base with which is in corporated a foot rest upon which a student may y comfortably rest 'his feet and 'which is so constructed as to prevent slipping.

A further object is toprovide 'a desk having oisetseat and top supporting devices permit-A ting a certain amountrof resiliency in the desk which is not'possible in a Acenter pedestal, andwhich Apermits a greater degree of comfortl for the student and efciency in the placement ofv the article holder than is possible with a center pedestal desk.

A further object is to provide a desk wherein` the seat and top are properly balanced on the' pedestal and'base'so that it is not necessaryto fasten thebase to the floor. To the above objects and to others which ma hereinafter appear; theinvention consists of the novel construction, combination and arrangement of parts as will be more specically'referred to and illustrated in the accompanying drawings,

wherein are illustrated embodiments of the invention, but it is to be understood that changes, modifications and Variations may be resorted to which fall within the scope of the invention as claimed.

In the drawings:

Figure 1 is a detail side elevation of a chair and desk constructed according to an embodiment of this invention,

Figure 2 is a sectional View taken on the line 2-2 of Figure 1,

Figure 3 is a sectional view taken on the line 3--3 of Figure 1,

Figure 4 is a sectional View taken on the line 4-4 of Figure 1,

Figure 5 is a bottom plan partly broken away of the base,

Figure 6 is an enlarged fragmentary sectional view taken on the line 6-6 of Figure 1,

Figure 7 is a fragmentary sectional view taken on the line of Figure 6,

Figure 8 is a sectional view taken on the line 6-8'of Figure 7,

Figure 9 is a fragmentary rear elevation of a portion of the pedestal or standard structure, and

Figure 10 is a side elevation of the pedestal clamping means.

Referring to the drawings and rst to Figures 4 and 5, the numeral 40 designates generally a base structure which comprises a body having upwardly` inclined walls 4|, 42, 43 and 44. The outer lower end of the wall 4| is formed on a concave asat 45 and the lower end of the wall 42 is also formed concave as at 46. The wall 43 which is the rear wall is formed concave as at 4`| and the wall 44 which is a side wall is formed concave as at 4,8. A cushioned shoe structure generally designated as 45 is secured to the under side of the base 4D. The details of the shoe structure 49 are embodied in my copending application Serial No. 272,486, led May 8, 1939, which has issued as Patent No.` 2,228,382 of January 14, 1941.

The base 4D on the underside thereof is provided with angularly disposed bracing ribs 50 which are disposed at a substantially right angle to each other and intersect each other in the center of the base 40. The base 40 on the upper side thereof is provided with a transversely extending ridge or raised part 38 forming a foot, rest andridges 33 are formed in the walls 4| and 43 to coact with the ridge or rest 38 in holding a foot against slipping. The base 40 on the upper side thereof is provided with a hollow pedestal or standard 5| which is formed integral with the base 40 and is disposed at one side of the center of the base 40 as shown in Figures 4 to 6 inclusive. In Figure 4, there is shown in full linesi and in section the lower pedestal member 5| which is in the center of the base 40 with respect to the front and rear edges of the base 4D. The pedestal member 5| is cast integral with the base 40 and it will, therefore, be understood that Where the position of the pedestal 5| relative to the base 40 is to be changed, the pedestal 5| is cast with the base 4|) in such changed position.

The pedesta1 5| is made hollow with a vertically disposed channel 52 disposed therein and an upper pedestal member 53 is engageable in the channel 52 and is vertically adjustable relative to the lower orxed pedestal member 5|. The lower member 5| is provided in a side wall 54 thereof with a plurality of teeth 55 fmjming` a ratchet rack which is cast integral with the Cil ,. alternately. release and engagethe teeth 6| with,`

pedestal member 5|. The movable pedestal member 53 comprises a front Wall 56, side walls 51 and 58 and a rear wall 59. The rear wall 59 is provided with an elongated slot 60 therein which opens through the lower end of the rear wall 59 and the side wall 57 is formed with an inset part provided at the lower end thereof with teeth 6| which are adapted to selectively engage the teeth 55 so as to hold the movable pedestal member 53 in vertically adjusted position. The inner face of the front wall 56 is provided with a plurality of bracing ribs 62 more clearly shown in Figure 6 so as to brace the noi/able member 53. 'Ihe upper end 63 of the lower member 5| is provided with a threaded set screw 64 which is adapted to engage the side wall 58 of the upper member 53 so that the upper member may be locked in its vertically adjusted position relative to the lower member 5|. The set screw 64 also provides a means whereby in case of serious schoolroom abuse in excess of normal in which there is a noticeable deflection of the seat, the relative position of the stem or pedestal member 53 under the seat and the pedestal 5| can be readily corrected.

The uppr member 53 is adapted to be clamped in its adjusted position by means of a clamping block 65 which as shown in Figure 8 is substantially T-shaped in transverse section, the stem portion 66 thereof` engaging in the slot 60, and the head or flanged portion 61 engaging interiorly of the upper member 53. A plurality of bolts 68 engage through the rear wall 69 of the lower member 5|. and are threaded into the clamping block 65. The lower member 5| is provided with theV channel 52 thereof which is substantially wider than the widest width of the upper member 53 as shown in Figure 8 so that the set screw 64 may be used in order to adjust the inclination of the upper member 53 relative to the lower member 5|. In other words, the upper member 53 may be tilted out of the vertical for the distance permitted by the difference between the widthv of the channel 52 and the width of the upper member 53, the set screw 64 being adjusted in or. out so as to vary the inclination of the upper member 53 to the desired degree and thus correct any schoolroom abuse which affects the position of the seat relative to the iloor.

Thefmovable member 53 at its upper end is provided with a horizontally disposed substantially yoke or U-shaped seat supporting member T0. This seat supporting memberl is formed integral with the movable pedestal member 53 arid comprises. an upper plate 1| provided with degendngvbrfacins flanges 12 about the marginal edges thereof= A laterally and horizontally disposed flange 13, extentie.A from the bight of the seatsupportins member'lilon theA outer side of the. bieht, and. inwardly projecting ange or. plate, 74 extends inwardly of the bight of the plate, 7|. rIihe seat `supporting member 'l0 is adapted to beV secured` to a seat member 15 by means of fastening, members 'I6 which engage through the supporting member 1D and through the flange '13.

In. the use and operation of the desk structure shown in Figures 1 to 10 inclusive, the seat 15 may be adjusted vertically by' loosening the clamping member 65 and then moving the upper pedestal4 part 53,f upwardly or downwardly and at, the4 same time rocking this member so as=to selected teeth 55 in the pedestal member 5|.

After the height of the seat 15 has been determined, the clamping member 65 may be tightenedvand the inclination of the seat 15 may be adjusted by means of the set screw 64.

What I claim is:

A pedestal structure for a combined seat and desk, comprising a base formed of sloping front and rear walls and opposite side walls, a lower upstanding rearwardly inclined standard integral with one of said sides and disposed closely adjacent the outer edge of said one side, said lower standard being positioned medially between the front and rear edges of said front and rear walls, said lower standard being tubular and formed of front and rear walls, and inner and outer side walls, teeth carried by the inner side of said outer side wall, an upper tubular standard tele. scoping into said lower standard, said upper.

said slot and the flanged portion thereof bearing against the inner face of said upper standard rear wall, a bolt extending through said lower standard side wall and threaded into the stem of said clamping member, and a seat supporting member secured to said upper standard and overlying said base.
